ACC terminal
Cigar-Plug connection
Ext. Power jack
Battery
DC cable
Be sure the vehicle has a negative-ground, 12VDC electric system before installation. Connect the
provided DC cable directly to the battery as shown below to minimize any possible ignition noise.
Be sure the vehicle has a large capacity battery as the use of the transceiver may overload the
electric system of the vehicle.
If the ignition-key on/off feature is desired (optional feature), use the optional EDC-37 (For direct
connection to the circuit on the vehicle) or EDC-43 (for a Cigar-Plug connection. EDC-36 is also
compatible) cable. Connect one of the cables between the ACC terminal or a Cigar-Plug that operates with the vehicle ignition or ACC switch on the vehicle and EXT POWER jack on the rear side
of the unit. (Note: In many cars, the cigar-lighter plug is always powered. If this is the case, you
cannot use it for the ignition key on/off function.) If this option is selected, the unit can be turned
on/off either manually or automatically in accordance with the ignition key position:
1.
When the ignition key is turned to ACC or ON (Start) position with the radio turned
off, the power switch illuminates. The illumination will be turned off when the ignition key is turned to the off position. To turn on the unit, press the power switch
manually while it is illuminated (while ignition key is at ACC or ON position).
2.
When the ignition key is turned to ACC or ON position with the radio's power switch
on, the unit turns on automatically and the power switch will be lit. Turn the ignition
key to OFF position or manually turn the power switch off to shut down the radio.
The power consumption when using the additional cable is 5mA.
For operation without this option, use the power switch to turn the unit on/off.
Power supply voltage display function
After connecting the transceiver to the power supply, the supply voltage can be confirmed by
pressing the SQL key together with the FUNC key. The supply voltage to the transceiver is then
seen on the display.
The transceiver will return to its normal operation when the power is switched OFF.
The display immediately changes as the voltage supply changes.
It also displays voltage during transmission.
IMPORTANT: The range of the displayed voltage is only from 7V - 16VDC. Because the displayed value
is estimated, please use a voltmeter when a more precise reading is desired.

Squelch level setting
A squelch eliminates white-noise (the background noise when
a signal is not received).
Higher level settings will keep the squelch “closed” more
tightly for quieter monitoring, but weak signals will not be
heard. Lower settings allow weaker signals to “open” the
squelch but noise may also cause it to open.

By rotating the main dial or by using the UP/
DOWN keys on the microphone, adjust the
squelch to the desired level. To return to normal use, press PTT or any key on the front
panel; or if there are no operations within 5
seconds, the unit will store the setting and will
return to its original status.
The new squelch level will be stored in the CPU until another
adjustment is done.

5. Basic Operation
VFO mode
VFO tuning is set as a default mode at the factory. VFO (variable frequency oscillator) allows you to change the frequency
in accordance with the selected channel step as you rotate the
main dial or by using the UP/DOWN keys on the microphone.
VFO mode is also used to program the data to be stored in the
memory channels or to change the parameter settings of the
transceiver.
1.
Identify the current mode by checking the display. If “M” or “C” icon is NOT displayed on
it, the unit is already in the VFO mode.
2.
Otherwise press “V/M” keys until those icons
are gone.
VFO mode
[Change frequency by the channel step]
Rotate the main dial clockwise to increase the frequency, counterclockwise to decrease. The UP/DOWN keys on the microphone act in the same way.
[Change frequency by 1 MHz step]
This will enable a quick change of frequency in 1 MHz steps:

on the front panel to enter the desired step into
the transceiver’s memory. The display will then
return to the original status.
Please note that settings below 10 kHz may be automatically
corrected according to the selected step.
REPEATER (DUPLEX) Operation
Shift Direction and Offset frequency setting
Conventional repeaters are operated in the DUPLEX mode.
It receives an incoming signal (UP-LINK) on one frequency
and re-transmits on another (DOWN-LINK). The difference
between these two frequencies is called the offset frequency.
If the UP-LINK frequency is higher than the DOWN-LINK
frequency, the direction is positive, and if it is lower, the shift
direction is negative. The offset is variable between 0 to 99.995
MHz on this unit.
Press the F key. While the F icon stays on the display, press
MHz key. The display shows the current status of shift direction and offset frequency. The default value is 0.60 MHz (600
kHz) in the negative direction. Press MHz key until the desired offset direction is set. If SIMPLEX mode (without changing transmit and receive frequency) is desired, select the position where both - and + icons disappeared.

Shift release
1.
Rotate the dial or use UP/DOWN keys on the microphone to change the shift frequency. It changes in accordance with the channel step setting.
2.
In this mode, if the F key is pressed again, the offset frequency can be changed in
1 MHz steps for faster setting.
3.
Press PTT or any key except F or MHz on the front panel to return to the original
status.
15
5. Basic Operation
CTCSS / DCS setting
Many repeaters require a CTCSS tone or a DCS code encode setting as a “key” to access the
system, so-called “selective-calling”. Sometimes, CTCSS or DCS decode features are used on the
output of a repeater so they can be used as a squelch. In this mode, regardless of the main squelch
status, the audio can be heard ONLY when the matching tone/code signal is received. The combination of CTCSS squelch and DCS function is not available; only one or the other may be used for
a given memory channel.
1.
Press TS/DCS key. The current setting will be
displayed with T/SQ/DCS icons and relative
frequency/code. Press the same key to select
T/SQ/DCS setting.
T
88.5
T/SQ
88.5
DCS

The original status
2.
The numbers (such as 88.5) represent the CTCSS frequency in Hz. When it is displayed with the T icon only, the unit transmits the sub-audible tone while the PTT is
pressed (encode) and the repeater access is enabled (assuming the repeater is using
88.5).
3.
Press the same key again so that the SQ icon shows up on the display. This is the
CTCSS decode frequency. This enables CTCSS squelch (or Tone Squelch, TSQ).
4.
Press it again so that the 3-digit number and DCS icon is displayed. This is the DCS
code, and it enables DCS encoding and decoding.
For 2 - 4, rotate the main dial or press the UP/DOWN keys to change tone or code. Press any key
(Except TS/DCS, UP/DOWN keys) to enter the setting and return to original status. The T/SQ/
DCS icon will remain on the display to show the current status. To exit, simply use the TS/DCS key
and press it until the relative status icon T/TQ/DCS disappears.
The CTCSS encoding and decoding frequencies may be set differently. The encode setting frequency automatically relates to the decode setting, but decode setting does not affect encode. The
standard set of 39 different CTCSS tones are available as shown on the chart below. DCS encode/
decode cannot be separated and are selectable from 104 codes as shown below.

[Programmable data in the memory channel]
Some features will be explained later, so please read this instruction manual thoroughly prior to
programming memories.
Memory channels including 0 - 99 and CALL can store following:
• Frequency
• Shift frequency
• Shift direction
• CTCSS tone both encode and decode
• Tone Squelch setting
• DCS code both encode and decode
• DCS squelch setting
• Scan skip channel
• Busy Channel Lock Out setting
• Priority monitoring frequency (PC programming required)
• Normal/Narrow FM width
• AM air-band receive (available on DR-135T only)
NOTE:
18
Only the frequency can be stored in PH and PL channels to determine the edges of the program
scan range.
5. Basic Operation
CALL mode
This is a memory mode that allows the DR-135 to quickly recall the assigned memory channel by
simply pressing the CALL key, regardless of the current status of the unit. The default CALL
frequency is 145.00 MHz.
1.
Press CALL key. The C icon appears on the
display and the transceiver enters the CALL
mode. In this mode, the main dial or the UP/
DOWN keys cannot change the frequency or
memory channels.
2.
Press CALL key again or press V/M key to exit
CALL mode.
3.
No scan functions are available in CALL mode.
To store a desired setting in the CALL channel, follow the memory mode programming instructions and assign your selected settings to memory channel C. The call channel can be modified but
cannot be eliminated or hidden.
To receive signals
• Be sure to have the unit connected to the appropriate antenna, powered on, set the audio volume and
squelch level properly.
• Select the desired receiving frequency or browse frequencies to listen to ongoing communications. The
S-meter shows relative signal strength between BUSY and FULL when the transceiver detects an incoming
signal.
• If the S-meter indicates an incoming signal but nothing is heard from a speaker, check audio level, squelch
level, and CTCSS/DCS decoding status, which are explained elsewhere in this manual.
• A Monitor function is available to receive weaker signals. Press and hold SQL key for more than 1 second.
Regardless of the level setting of the squelch, it will be opened and the BUSY icon turns on the display.

MID power
HIGH power
4.
20
If operating from a vehicle, do not transmit for
extended periods without running the engine,
to avoid battery drainage. Check the battery
voltage often. The lights, windshield wipers,
stereo system, air-conditioner, defogger and
other accessories drain the battery’s power considerably. When those accessories are turned
on, reduce the output power or turn off one or
more accessories to avoid the battery becoming overloaded. Watch the road when driving.
Check local regulations that may pertain to the
use of a transceiver when driving.

6. Parameters Setting Mode
Time-Out-Timer
The TOT feature is popular in repeater systems. It prohibits the users from transmitting on the
repeater after a certain period of time has elapsed. By setting this function and activating it according to the repeaters’ requirement, the radio alerts the user by a beep 5 seconds prior to time-out.
When the time is expired, transmitting stops and the transceiver automatically returns to receiving
mode. This avoids the repeater going into its TOT mode. Until the PTT is released once and pressed
again, the DR-135 will not transmit.
1.
In this Menu the default display shows TOTOFF.
2.
Rotate the main dial to select time-out time.
The display should change as shown. The number followed by TOT is the time-out time in

NOTE:
• Never connect a PC directly to the DSUB-9 connector if EJ-41U is not installed. It may
cause the unit to malfunction.
• The local system, transmission and reception environment may easily cause troubles in 9600bps
packet mode. A connection error may frequently occur unless the communication is established
at very high signal strength.
• When the DATA input level is far off from the specification (1200bps=100mVrms/600ohm,
9600bps=400mV/600ohm), it causes poor S/N ratio and distortion, as such the data will not be
exchanged properly.
• When the radio is in the data mode (packet/APRS®), selective calling tones such as DCS and
CTCSS won’t be transmitted.
[To operate APRS®]
APRS® is a trademark of Mr. Bob Bruninga, WB4APR. Using the designated APRS frequency in
your area, and a system composed of the transceiver, EJ-41U (or TNC) a computer and/or a GPS
receiver, you may monitor and exchange various geolocating information on the PC and on the
internet. Details are available from Internet sites.
The radio is capable of being connected to an EJ-41U (or TNC), PC and GPS receiver. To enjoy
APRS operation, a GPS receiver, computer and APRS software are required in addition to the
packet (data) operation system previously mentioned. Purchase a NMEA (National Marine Electronics Association) compatible GPS receiver with a data output port.
• Specifications required for the GPS receiver: NMEA-0183, 4800bps/without parity bit/data length

8. PACKET OPERATION
[SET UP]
Please refer to the previous chapter for the set up and installation of the EJ-41U unit, TNC and PC.
See below for the connection of a GPS receiver. It requires a 3.5mm stereo plug to connect to the
DATA Terminal on the radio's front panel. See the chart for plug connections. Program the EJ-41U
by using commands from the PC in the same way as in the packet mode.
